“…Thus, it has a wide range of potential applications, including bio sensors, photovoltaic devices, gas sensors, humidity sensors, vapor sensors, and pressure sensors (Dubey & Gautam, 2009;Dubey, Patil, Bange, & Gautam, 2007;Agarwal & Del Rıo, 2003;Oton et al, 2003;Setzu, Ferrand, & Romestain, 2000;Salcedo, Ramirez Fernandez, & Galeazzo, 1997). PS can also be used for anode materials of Li rechargeable batteries because of its larger surface (Mizsei, 2007;Jalkanen, Tuura, Mäkilä, & Salonen, 2010). Fabrication of PS micro cavity as optical sensor device (Mishra, Patel, & Vohra, 2014).…”
